Abstract：Multi-agent cooperative decision-making is capable of overcoming incomplete knowledge of single agent and improving reliability of the results. In this paper, the reliability of agent is studied on the basis of the evidence theory based multi-agent cooperative decision-making mechanism. A definition of agent reliability is proposed to characterize the reliability of single agent and agent group. Agent fitness is introduced to describe the dynamic reliability of agent during decision-making process, and the agents are optimally chosen for cooperative decision-making. The experimental results show the proposed algorithm effectively decreases computational complexity of combining multi-agent conclusions.
